197: CHAPTER 1 TYPES AND STAGES OF DESIGN PROJECT

1. TRADITIONAL (DESIGN-BID-BUILD)

2. DESIGN AND BUILD

TYPES OF DESIGN PROJECTS

TRADITIONAL (DESIGN-BID-BUILD)

• Owner hires a designer to design the facility and prepare drawings and specification for bidding

• Contractors reviews the drawings / specifications, ask any clarifying questions and bid for the project based on the drawings / specifications

• Designers may be asked to attend meetings to address any design issues during the bidding / construction stage

• Consultant/Peer Reviewer to review the output of designer

DESIGN AND BUILD

• Owner prefers to transact with a sole entity

• Accelerates the construction timeline since the contractor has direct communication with designer

Contractor has autonomy in the design.

SAMPLES OF Desktop Study

Geodetic Surveying

• Establishment of contour elevations

• Verification of Lot Plan

• Mapping of Obstructions

Geotechnical Investigation

• Establish soil bearing capacity / pile capacity

• Provide recommendation for foundation type and depth of embedment

• Liquefaction Analysis

Environmental Impact Assessment

• assessment and evaluation of the environmental impact of a project during its whole construction / operational life

• includes preventive / mitigation measures to the identified impacts to protect the environment and the community
